Kate Middleton gets candid about parenting Prince Louis

The Duke and Duchess of Cambridge are relatively private when it comes to their three children. However, the Duchess has shed some light on her life as mum of three, telling some royal fans just how mischievous her youngest son is.

Kate, 37, visited Bletchley Park on Tuesday to open a new exhibition at the restored Teleprinter building. Bletchley Park is a Victorian museum dedicated to those who broke the German codes during WWII communications.

Along with meeting young budding de-coders, the future Queen consort met with four women who had worked there at the same time as her grandmother Valerie and great-aunt Mary, one of whom congratulated her on her “beautiful family.” In response, the Duchess told the women about her mischievous youngest son, Prince Louis, telling them the one-year-old was “keeping us on our toes.”

Prince Louis, the little brother of Prince George and Princess Charlotte, recently celebrated his first birthday. His April birthday came only weeks before the birth of his new cousin, Archie Mountbatten-Windsor.

Catherine has previously told fans she would like to have a big family and confirmed she and her husband Prince William were not against having more children.
